One of the last things that a homeowner often thinks about is washing their roof. When thinking about roof maintenance, everyone thinks about activities like removing debris from the gutters and sweeping the surface. However, you can soft wash the roof using a low-pressure stream and specific solutions to cleanse the stains. The cleaning is ideal for rooftops that have started accumulating mold, mildew and algae, and other organic stains. The cleaning process is practical and efficient.
